Certainly the Internet is the most conspicuous example of computer networking. Allows many different devices in multiple locations to access a shared repository of data LAN : LAN Within a Building or Campus A high-speed data network that covers a relatively small geographic area. It typically connects workstations, personal computers, printers, servers, and other devices. Slide 6:  What Is a WAN? Network that covers a relatively broad geographic area WAN technologies generally function at the lower three layers of the OSI reference model: the physical layer, the data link layer, and the network layer. WAN (Wide Area Networking) A Typical Point-to-Point Link Operates Through a WAN to a Remote Network: WAN : WAN DELHI CHENNAI WAN Link DELHI CHENNAI Slide 8: Recent trends in networking “Bluetooth wireless technology is an open specification for a low-cost, low-power, short-range radio technology for ad-hoc wireless communication of voice and data anywhere in the world.” Slide 9: Recent trends in networking Technical features Ultimate Headset : Recent trends in networking Ultimate Headset Cordless Computer : Recent trends in networking Cordless Computer Bluetooth Goals & Vision : Recent trends in networking Bluetooth Goals & Vision Originally conceived as a cable replacement technology Short-Range Wireless Solutions Open Specification Voice and Data Capability Worldwide Usability How to install bluetooth software in PC : Recent trends in networking How to install bluetooth software in PC Step 1 Step 2 How to install bluetooth software in PC : Recent trends in networking Step 3 Step 4 How to install bluetooth software in PC PC’s Environment : Recent trends in networking PC’s Environment Here a PC and k550i is connected Slide 16: Recent trends in networking Security measures Supports Authentication Encryption & Decryption Authorization Identifiers ID’s Random numbers Private Keys Long encryption keys are used Wireless Fidelity (Wi-Fi)Welcome to the World of Wireless : Recent trends in networking Short form of Wireless Fidelity. This can be defined as a wireless Local Area Networking System. Can you imagine a day without Internet? For me it is not possible. That means now internet has become an integral part of our life.
